5 claims.

My invention relates to improvements in lamp posts oi wooden structure such as are desirable for use along illuminated parkways and other highways. Generally stated, the invention consists of the novel construction, arrangement and combinations of parts hereinafter described and defined in the claims. Particularly, the invention is directed to improved means for iorming cable che-ses on conduits for wooden posts equipped with electric lamps.

The invention is illustrated in the accompanying drawing wherein like characters indicate like parts 'throughout the several views.

Referring to the drawing:

Fig. 1 is a side elevation;

2 is enlarged side elevation of the post with parts broken away and with some parts in vertical section;

Fig. 3 is a rear elevation oi' the upright portion or post proper of the complete lamp post, some being broken away;

Fig. i is a horizontal section taken on the line of Fig. 2;

i'ig. 5 is a fragmentary enlarged section taken on the sarne line as Fig. 4.;

Fig. S is a perspective showing the outer portion the arni oi the post sectioned on the line 6-6 Fig. 2; and

Fig. 7 is a fragmentary section on the same line as Fig. 5 illustrating a slightly modied construction.

The body of the post is indicated by the numeral 7, the arm by the numeral 8 and the arin brace hy the numeral 9, which parts are wooden inembers which, `for ornamental purposes, will usually have hand-adzed surfaces. The cross arm 8 is narrower than the post and is extended through a inortice formed therein and is anchored thereto by a pin l preferably also a wooden member. The brace 9 at its obliquely cut ends, is formed with tenons 1l i u into the seats formed in the post 7 and 8. The post 7 at its hack side is formed with a longitudinally extended dove-tailed groove 12 and inward thereof with a narrower longitudinal groove or chase 13 that forms a conduit for a cable 14 that contains the wires that lead from a point under ground to the electric lanip presently to he noted. At its upper extremity the dove-tailed groove 13 and conduitforming groove 14 terminate at the under side of the arin S and join, respectively, with a correspondingly formed dove-tailed groove 12a and conduit-forming groove 13aL formed in the under side of the arm 8. Here it will be noted that the conduit-forming groove 13a extends above the oi of 1932, Serial No. 63

upper tenen il of the upper brace 9 while the dove-tailed groove 12'L1 is intercepted or divi led by said upper tenen 1l. This permits horirontal upper portion of the cable lll to he extended to a point near the outer extremity of the rin 8 where said cable is joined by a T-coupling l o the like to the stem 15 of an electric lamp 1'?. Said stern 16 extends through the 8 suitably secured thereto.

To close the dove-tailed groove i2 and house-in the vertical portion of the cable le, a wooden wedge structure is e'nployed. This wooden wedge structure, as preferably designed, comp ises two wooden members, to wit: a wooden filler strip 1.3 and a wooden key 19, which when ass-einhled, completely ll the dove-tailed groove l2, see s. 4.- and 5. The ller strip 1S is a dove-tailed meinher while the key 19 is a supplier. t thereto and is preferably slightly tapered inwardly in horizontal cross-section. in placing the complete wedge in position, the rneinher 1S is first located in the groove 12 and then *he member 19 is pressed or forced into position, which action, however, does not require inuch pressure. To securely hold the assembled wedge structure in the post, a plurality oi screws 2O used and these are preferably passed into the body of the post through the joint formed between the wedge members 18 and 19. Fig. 3 shoe/s an assembled wedge structure 18-19 positioned and held the screws 29.

The dove-tailed groove and the arm and is made up or" a wood iiller s wooden key 1Q, that correspon respectively to the members 18 and le. In the 8, however, the ller strip 182L and lrey 19a extended between the post and the tenori ll and then between said tenori and the cour .g 15 oi the outer portion of said The finer s1 ip 18a and key 1Qa are held in position hy screvs 202L applied in the saine manner as the screws The groove and wedge structure descr1 affords a highly efcient for conc-3a cable within the post arm. Such st.- i can be made at comparatively sinall -cost and be very quickly assembled either at the factory or at the place of assemblage, and moreover, the wedge structure does not the post lout be embedded into the saine in such a way that it may be scarcely perceptible.

A preferred arrangement has been illustrated in the drawing and specincally described, hut it may be understood that modifications may be Gil CTL

made within the scope of the invention herein disclosed and claimed.

The slightly modified structure of Fig. '7 is like that illustrated in the other views and best shown in Fig. 5, except that the groove 12b that receives the wooden wedge structure is rounded at one side and both sides of the key member v19b are rounded to fit one rounded side of the filler strip 18h.

In this arrangement, the walls of the wedge 18h are preferably parallel or, in other words, concentric, so that the wedge, while removable, will not be accidentally removed. Ii greater security were desired, brads or nails or the like might be driven through the outer portion of the key 19b into .the strip 18h.

What l claim is:

1. A wooden post having a longitudinally extended Wedge-receiving groove and inward thereof a narrower cable-receiving chase, a wooden wedge structure filling said groove and closing said cable-receiving chase, said wedge structure comprising a dove-tailed filler strip and a supplemental key, and displaceable metallic anchors normally holding said structure in place.

2. The combination with a wooden post and a wooden arm extended therefrom, one side of said post and one side of said arm having conduitforming and filler-receiving grooves in communication at the junction of said post and arm, and Wooden iillers closing said wedge-receiving grooves in said post and arm to enclose a cable Within said post and arm, the filler closing the groove in the post being removable to afford access to the groove in the arm.

3. The structure deiined in claim 2 in which said Wooden llers comprise dove-tailed filler strips and co-operating supplemental keys, said supplemental keys being tapered in cross-section, and removable anchors removably holding the key in the post in an operative position.

4. The structure defined in 'claim 2 in further combination with an oblique wooden brace connecting said post to said arm and having a tenon inserted into the under side of said arm below the conduit-forming groove of the latter, but between sections of the wooden fillers that close the ller-receiving groove of said arm.

5. A wooden post having a longitudinally eX- tended Wedge-receiving groove and inward thereof a narrower cable-receiving chase, and a wooden Wedge structure filling said groove and closing said chase, said Wedge structure cornprising a dove-tailed ller strip convexly curved on one side, and a supplemental key concavely curved on one side and convexly curved on the other side.
